title: Occurrence of bio-immuno active inhibin in rat spermatids.
abstract: Levels of inhibin in the spermatocyte and spermatid enriched fractions of rat testicular extract were estimated using a specific and sensitive radioimmunoassay. The fraction enriched in spermatids had the highest amounts of inhibin activity. The results of the study indicate that the spermatids may be likely source of inhibin.
